Set van 2 oude vintage speakers van het merk adc, model 303 ax, met een mooie houten uitstraling. De grote woofers zijn nog intact en functioneren. De kleine bovenste speakers/tweeters zijn beschadigd
These are a respected early-70s vintage pair with a genuinely good rep for smooth, balanced sound and usable bass, and €45 is a strong buy if both speakers are complete and working. Comparable used examples have recently surfaced around about €70 to €180 a pair, with rougher or incomplete sets lower, so this sits below the usual going rate and looks like a bargain.
The appeal here is straightforward: classic New England-style voicing, easy amp matching, and enough scale for small-to-medium rooms without sounding fussy. At this price, the main upside is getting in cheaply on a model that can be very satisfying when original and healthy; just verify both woofers, tweeters, and cabinets are intact, since age-related driver or crossover issues matter more than cosmetic wear on a vintage piece like this.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
ADC most likely refers to Audio Dynamics Corporation, a U.S. hi-fi brand founded by Peter Pritchard in the early 1960s in New Milford, Connecticut. It should not be confused with ADC Telecommunications, which was a separate communications company. The audio brand’s heritage is firmly rooted in the classic American cartridge era, and it later passed into other ownership before disappearing as an independent maker.
ADC was best known for magnetic phono cartridges, especially high-performance models aimed at vinyl playback. Its identity was tied to turntable-era analog audio rather than a broad component catalog, and there is no strong evidence that it became a major player in amplifiers, speakers, DACs, or headphones.
In market terms, ADC sits today as a vintage-collector and analog-audio specialist brand rather than a current mainstream hi-fi label. Among knowledgeable buyers, it is remembered for inventive cartridge design and respectable sonic performance, with interest driven more by restored legacy products and archival reputation than by an active modern product line.
